After being held to a season-low 8 points in their first loss of the season last week to league champion O’Bryant, the Dragons’ offense redeemed itself, manufacturing two scoring drives in the victory. Also contributing on the scoreboard was the defense, which add 8 points on a safety in the second quarter and a fourth-quarter fumble recovery in the end zone by senior Cristian Mojica. Those points turned out to be the difference in the game.

“It was a tough game for us in the sense that we’re two even teams. Coming into this game we knew it was going to be a dogfight, we really did,’’ said Latin Academy coach Rocco Zizza. “And give credit to my teammates because they really bounced back after a tough loss last week. We didn’t play well last week, but we really showed up today, particularly our defense.”

The Bears (5-3) scored first on a 2-yard TD rush by Hakim Harris. After the first quarter, though, LA (7-1) scored 16 unanswered points, starting when senior quarterback Kyle Dance hooked up with DeVaughn Riley on a slant pass from 33 yards out just before halftime.

In the third quarter, LA got a big break after Dance was picked off by Demetrius Leary, who tried to run it out of the end zone and got pinned on the 3-yard line. A fumble, recovered by Mojica, made it 16-6 LA.

Latin Academy will play O’Bryant in the sectional semifinals next weekend. O’Bryant beat LA, 21-8, last weekend.
